System and method for secure communication

ABSTRACT

A system and method for securing communication through a device that is able to trigger an offline physical event through an online communication process.

FIELD OF THE INVENTION

The present invention is of a system and method for secure communication, and in particular, of such a system and method for securing communication through a device that is able to trigger an offline physical event through an online communication process.

BACKGROUND OF THE INVENTION

Currently there is a significant problem for controlling real world events, such as ordering products, through an online environment. On the one hand, organizations such as corporations, hospitals, schools and so forth may wish to provide ease of ordering products for their staff and customers. Requiring multiple layers of permissions and authorizations for ordering such products can result in significant time wastage and effort for the staff and customers. On the other hand, reducing such bureaucratic procedures may result in unauthorized and wasteful orders being placed. Unfortunately, there is no currently available solution which is both able to provide control over offline events through an online system, yet which does not require the navigation of a complicated bureaucratic procedure.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes the drawbacks of the background art by providing a system and method for securing communication through a device that is able to trigger an offline physical event through an online communication process. The trigger(s) determined by the device are preferably controlled through a separate application, which may be controlled through a user computational device and/or a server. The separate application sets the one or more triggers accessible to the device and also determines one or more conditions for activating the one or more triggers. Upon detection of one or more conditions by the device, one or more triggers are activated. The user computational device receives a notification of the activation of the trigger. The user computational device may modify the trigger, the activation of the trigger or the one or more downstream actions which occur upon activation of the trigger. Such modification may occur before activation of the trigger or after activation of the trigger.

Turning now to the drawings, as shown in FIG. 1A, there is provided a set of views of an internet of things, or IoT, device. As shown in a plurality of views, a device 100, features hardware for authentication that preferably does not require a fingerprint. The view at 100 shows a power button. A side view is shown at 101, a front-end view 102, another side view at 103, a view at 104, and a back view at 105. Front-end view 102 includes a plurality of buttons, at least 1 and optionally up to four buttons, as well as an optional LED to indicate status. Optionally device 100, or any IoT device described herein, comprises a sensor in addition to, or in place of, one or more buttons for receiving direct input for determining an action to be triggered. At 103, a slot is shown to permit a cellular connection, for example for a SIM card or a micro-SIM card. The view at 103 also shows a charging port. View at 105 shows exemplary feet or rubber padding.

FIG. 1B shows a non-limiting exemplary device docking station shown in two embodiments, 106 and 107, for permitting the devices to dock and recharge. In view 106, the device is showing coming into the docking station and in 107, the device is showing as fully docked. Optionally, up to six devices 100 are charged in the docking station.

FIG. 1C shows an internal flow for the operation of the device. As shown in device, 100, power is preferably received through a micro-USB port 120 and then flows to charging unit 122. Charging unit 122 then charges a battery 124 as needed. Battery 124 enables device 100 to operate without being connected to the docking station as shown in FIG. 1B, or another source of power, except as needed to maintain a required charge on battery 124.

A power regulator 126 supplies power from battery 124 to an optional fingerprint module 128, for optionally identifying a user of device 100 through a fingerprint. Power regulator 126 also supplies power to a MCU (microcontroller unit, 130), which manages overall functionality of device 100. Device 100 is turned off and on through a power switch 132.

Power switch 132 further controls power to a key 134 and switches 136. The combination of key 134 and switch or switches 136 forms a button as previously described, for being activated by a user through pressing the button, for example. Power switch 132 further controls power to a connectivity module 138, which may for example include cellular or WiFi connectivity as described herein.

As shown in FIG. 2, a non-limiting exemplary flow for placing an order is shown. An order may include but is not limited to, ordering a product or service to be provided or delivered; or causing any electronic action or set of actions to be performed. In a flow 200, the process for placing an order preferably begins by having a computational device, which may be, for example, mobile, tablet or PC, shown as computational device 201. Computational device 201 may for example be controlled by an authorized user. Computational device 201 comprises a processor 210A and a memory 212A. Each computational device or server as shown throughout the drawings would feature such a processor and memory combination, even if not shown for the sake of clarity.

Computational device 201 also preferably features a user interface (not shown, although it may be implemented through application 203). The user transfers commands through the user interface. Computational device 201 proceeds then to perform necessary actions, through instructions stored in memory 212A and executed by processor 210A.

As used herein, a “user interface” generally includes a plurality of interface devices and/or software that allow a user to input commands and data to direct the processing device to execute instructions. For example, the user interface may include a graphical user interface (GUI) or an interface to input computer-executable instructions that direct the processor to carry out specific functions. The user interface employs certain input and output devices to input data received from a user or output data to a user. These input and output devices may include a display, mouse, keyboard, button, touchpad, touch screen, microphone, speaker, LED, light, joystick, switch, buzzer, bell, and so forth.

As used herein, a processor generally refers to a device or combination of devices having circuitry used for implementing the communication and/or logic functions of a particular system. For example, a processor may include a digital signal processor device, a microprocessor device, and various analog-to-digital converters, digital-to-analog converters, and other support circuits and/or combinations of the foregoing. Control and signal processing functions of the system are allocated between these processing devices according to their respective capabilities. The processor may further include functionality to operate one or more software programs based on computer-executable program code thereof, which may be stored in a memory. As the phrase is used herein, the processor may be “configured to” perform a certain function in a variety of ways, including, for example, by having one or more general-purpose circuits perform the function by executing particular computer-executable program code embodied in computer-readable medium, and/or by having one or more application-specific circuits perform the function.

Computational device 201 may be used for registering and then configuring the IoT device 202 through an application 203. Once IoT device 202 has been configured, then the IoT device 202 may be used to place an order or invoke another event 204 through the application 203. Application 203 is optionally also accessed from a separate computational device 205, also shown as featuring a processor 210B and a memory 212B. The order may then be placed through the application 203. Optionally, another event may be performed at 204, once configuration has occurred and the IoT device 202 has been registered to place orders.

For example, optionally memory 212A of computational device 201 features a plurality of instructions, which, when executed by processor 210A, cause the execution of application 203. Preferably, memory 212A is configured for storing a defined native instruction set of codes. Processor 210A is configured to perform a defined set of basic operations in response to receiving a corresponding basic instruction selected from the defined native instruction set of codes stored in memory 212A. For example and without limitation, memory 212A may store a first set of machine codes selected from the native instruction set for registering IoT device 202 through application 203; a second set of machine codes selected from the native instruction set for configuring IoT device 202 according to one or more requirements, wherein such requirements are sent from application 203; and a third set of machine codes selected from the native instruction set for invoking an event by IoT device 202 through application 203.

Preferably, memory 212B is also configured for storing a defined native instruction set of codes. Processor 210B is configured to perform a defined set of basic operations in response to receiving a corresponding basic instruction selected from the defined native instruction set of codes stored in memory 212B. For example and without limitation, memory 212B may store a first set of machine codes selected from the native instruction set for accessing application 203, for example to place an order.

FIG. 3A shows a non-limiting exemplary data flow in the device, preferably connected to Wi-Fi, and also preferably without requiring fingerprint authentication. For operation as shown, the user may press any of the buttons on the device shown in 301. The device is preferably connected to a local Wi-Fi router, shown as router 302, that passes device data to the MQTT broker or cluster 303 through the Wi-Fi router. MQTT stands for Message Queue Telemetry Transport. An MQTT functioning component is typically implemented as a broker; a plurality of such brokers may be implemented in a cluster. MQTT is intended as a non-limiting example of an IoT communication protocol; other types of protocols could be used instead. The MQTT cluster is preferably hosted on a server in the cloud. Further details regarding the MQTT are provided below. The device is optionally connected to a Wi-Fi router using an Access Point mode in the device 301.

As shown in FIG. 3B, there is provided a data flow within the IoT device; in this case the device is connected to Wi-Fi, preferably with fingerprint authentication. As shown in process 305, the user presses any of the buttons on the device after fingerprint based authentication. Function block 305 includes fingerprint based authentication, and then supports the further pressing of a button on the device by the user, post-identification, to place an order. Fingerprint based authentication may be supported by any suitable hardware/embedded instructions (or firmware) combination.

The device is connected to a local Wi-Fi router shown as 306. It communicates with the local Wi-Fi router 306 to pass the data. The data can then be passed from the device to the MQTT broker or cluster 307 through the Wi-Fi router.

FIG. 3C shows a non-limiting exemplary dataflow within the IoT device, preferably supporting GSM communication or other cellular network communication, for example through a micro-SIM card. Optionally the device is configured without fingerprint authentication. In the process 309, the user presses any of the buttons on the device, while the device is preferably connected to a mobile network, shown as 310. The data is then passed from the device to the MQTT broker or cluster 311 through the GSM connectivity shown as 310.

FIG. 3D shows the data flow in the device for a GSM connection with fingerprint authentication in a process 313. The user is performing fingerprint authentication and then presses any of the buttons on the internet of things device. The device is connected to a mobile network shown as having GSM connectivity 314. The data is then passed from the device to the MQTT broker or cluster 315, through the GSM connectivity shown as 314.

FIG. 4A relates to a non-limiting exemplary end-to-end flow with the user's computational device. Device 404 is able to place orders as previously described upon authentication or at least a button push. As shown, a button press for actions is performed 405 to enable an order to be placed. However, the order can be controlled, such as for example through order cancelation. Preferably such control is provided through an administrator computational device 403. Computational device 403 is notified about the order at notification 406. In response, cancellation, modification or other types of control are shown as order modifications in 406, and are preferably performed by computational device 403. As described in greater detail below, once device 404 receives a request to place an order, notification goes to MQTT broker in the cloud (not shown). The MQTT broker then sends a notification of an event to the web application for the admin, which then notifies the computational device 403, for example.

As shown in FIG. 4B, there is an end-to-end client-side flow, as shown with illustrative details as a non-limiting example only. As shown, an admin or other user computational device 408 is able to connect on the client-side to a web application and server in 413. This allows the computational device, 408 which may, for example, be from admin, to control order setting, order for modification, cancellation, and so forth. Computational support is then provided through a server block 412, which communicates with the IoT device 411. This enables changes to be made in terms of the functioning of the IoT device 411, for example, to set a particular button for a particular type of order or some other type of functionality.

Server block 412 may also update the functionality which has been provided to IoT device 411 through a database 417, which may, for example, be an SQL database. Server block 412 may also listen to changes occurring at database 417, for example through web application 413. Further modifications through the client-side web application 413, may be, for example, to perform device configuration or registration activity 415, order related activity 416, including cancellation and modification. Optionally, device registration module 415 through web application 413 writes to database 417.

Order related activity 416 preferably triggers an email or text notification, shown as email and text notification service 414. This activity can include order placement or cancelation.

Customer order system 418 is a system containing the customer information, to support creating the order. For example, orders may be placed through customer order system 418 manually or automatically, already in place at the customer premises. The order system 418 may listen to changes at database 417, through an API notification, whether as a pull or a push system. As such changes occur, they may automatically trigger an order to be placed by customer order system 418, or a further layer of review may be required. If customer order system 418 is not present, then optionally orders are sent directly from server block 412.

As shown in FIG. 4C, a data flow is provided from the device to the client server. IoT device 419 communicates through Wi-Fi, GSM or some other communication modality with a server block. The server block preferably features a load balancer 420 for enabling data to be distributed among a cluster of MQTT brokers shown as cluster 421. MQTT broker operation is based on publisher subscriber model for data routing, as described with regard to the MQTT standard.

This in turn triggers a routing service, shown as 422, to route the order to a specific IoT core on the client server-side. The client server may then receive the trigger from the routing service to trigger a specific client server based on the device ID that is related to client server 423. Routing service 422 routes messages from brokers 421 to the correct end user or client server 423, of a plurality of such servers (not shown), which may be at various different locations, such as on the premises of a separate company, building, organization or the like.

As shown in FIG. 4D, there is provided a server-side data flow. This includes receiving data from the device through the load balancer shown as 424 to trigger a specific MQTT broker in a cluster of brokers 425, which may then trigger a randomly or otherwise selected router service from a cluster of such services 426 based on the shared subscription policy configured in the MQTT broker. Preferably, only one router service is triggered for a particular message, such that the message is locked to that specific router service, to avoid duplication of messages.

FIG. 4E shows a router service flow for authentication. The device ID received from the MQTT broker is then used by the router service for fetching the connection string. This is then used to select the responsive IoT core client to be passed to.

The router service communicates by getting a device ID from an incoming message in 427. The router service uses the device ID to fetch the IoT core connection string. The connection string will contain information about which IoT core to trigger. The router service sends this information to authentication block 428, which can then read the data to and/or write data from a database 429. Once authentication has been performed, it is sent then to one of a plurality of IoT core clients 430. IoT core client 430 is an entry point to a separate client server and acts as a messaging service for the publisher subscriber model.

FIG. 4F shows on the client server-side an exemplary order placement data flow. As shown, the IoT core client 431, which has received the order, communicates with a plurality of microservices 432. Microservices 432 provide support for further actions with the order, such as sending customer data and orders, for example, to one or more systems with customer and order information 433. The device configuration information using the device ID may be retrieved from database 434 and communicated to microservices 432.

As shown in FIG. 4G, there is provided a flow for the configuration of the device for specific actions on the client server-side. A computational device 435, preferably controlled by an admin, communicates with the web application 436. Web application 436 preferably writes device configuration information used in the device ID as an identifier for the IoT device to a database 437 to allow authentication and order activities to be performed.

As shown with regard to FIG. 4H, there is provided a client server expanded view. A computational device 440, which may, for example, be controlled by an admin, communicates with a web application 441 as part of a client server 450. Web application 441 then performs creation and deletion of new devices through IoT core 442. It further triggers microservices 443, which communicate with the IoT core 442 as triggered microservice, and further communicates with web application 441.

Microservices 433 preferably also write information to database 445. This database information in database 445 may also be communicated directly with web application 441. Microservices 443 may also communicate with the system with customer and/or orders data 444.

Such an order placement block or system, which permits communication for placing orders, for example, according to supplier data and orders received from microservices, which are in turn preferably received from the IoT core client. The system is then sent to the system with customer and core information and is written in a database. In terms of configuration block, an admin computational device may communicate with the web application for creation and deletion of new services at the IoT core. The IoT core triggered microservice may receive the trigger from the microservices once configured, and so forth as previously described.

FIG. 5A relates to a non-limiting exemplary admin role. An admin user 500, who was identified as an admin user through a particular computational device, may optionally through this computational device control association, registration, new devices 501. For a customer, it is an association 503, but for the system it's a registration 504. The admin functions 500, preferably also include configuration of the buttons, one or many, present on the device 502. A plurality of four requests, shown as request 505, 506, 507 and 508 for the purpose of illustration only and without intent to be limiting.

FIG. 5B relates to non-limiting exemplary end user roles. The end user through an end user computational device 510, or through a direct physical action on the device, preferably performs a button press with or without fingerprint 511. This button press may then result in one of a plurality of different requests being issued, such as 513, 514 and 515, or to cancel request shown as 512.

FIG. 5C relates to non-limiting exemplary data steward roles, which may be used, for example, to permit additional oversight on the data. A data steward computational device 516 may, for example, control order operations 517, including order rejection 518, approval of unauthorized orders 519, and order editing 520.
